Description

本発明は、複数の太陽電池パネルを電気的に接続するのに用いられる端子ボックスに関する。
特に端子ボックス内に組み込まれているバイパスダイオードの放熱構造に係る。 The present invention relates to a terminal box used for electrically connecting a plurality of solar battery panels.
In particular, the present invention relates to a heat dissipation structure for a bypass diode incorporated in a terminal box.

太陽電池パネルは、発電量の増大を目的に複数のパネルが電気的に接続されて用いられている。
しかし、太陽光が充分に当たらないパネルや故障したパネルが一部に存在すると、そのパネルの起電力が低下する。
起電力が低下したパネルは、他のパネルの電流に対する抵抗成分となり、電圧降下の原因となる。
そこで、他の良好な起電力を有するパネルから不良パネルを分離するのにバイパスダイオードが配設されている。
従って、バイパスダイオードには順方向への大電流が流れるため、発熱が大きく、適正な使用温度を確保するための放熱手段が必要となる。
このようなバイパスダイオードが組み込まれた太陽電池パネル用端子ボックスは、感電防止及び風雨による腐食の防止を図るために、樹脂製の筐体に組み込まれているのが一般的である。
そこで、樹脂製の筐体を用いながら、放熱効果の高い端子ボックス構造が要求される。 Solar cell panels are used with a plurality of panels electrically connected for the purpose of increasing the amount of power generation.
However, if there is a panel that is not sufficiently exposed to sunlight or a broken panel, the electromotive force of the panel decreases.
A panel whose electromotive force is reduced becomes a resistance component with respect to the current of other panels, and causes a voltage drop.
Thus, a bypass diode is provided to separate the defective panel from other panels having good electromotive force.
Therefore, since a large current in the forward direction flows through the bypass diode, heat generation is large, and a heat dissipating means for ensuring an appropriate operating temperature is required.
In general, a terminal box for a solar cell panel in which such a bypass diode is incorporated is incorporated in a resin casing in order to prevent electric shock and corrosion due to wind and rain.
Therefore, a terminal box structure having a high heat dissipation effect is required while using a resin casing.

特許文献１には、蓋板をプラスチック樹脂部材及び金属部材で形成し、筐体内部に面する面に金属部材が取り付けられているか、あるいは金属部材の周囲がプラスチック樹脂部材で包囲されている構造を開示する。
また、前記金属部材がバイパスダイオードに接触している形態についても言及されている。
しかし、バイパスダイオードの発熱が前記金属部材に直接伝導されるものではなく、放熱性が不充分である。
特許文献２には、バイパスダイオードを放熱板に取り付けた構造を開示するが、この放熱板だけでバイパスダイオードからの発熱を放熱させるのには、大きな面積の放熱板が必要となり、端子ボックスが大きくなる問題があった。 Patent Document 1 discloses a structure in which a cover plate is formed of a plastic resin member and a metal member, and the metal member is attached to the surface facing the inside of the housing, or the periphery of the metal member is surrounded by the plastic resin member. Is disclosed.
In addition, a form in which the metal member is in contact with the bypass diode is also mentioned.
However, heat generated by the bypass diode is not directly conducted to the metal member, and heat dissipation is insufficient.
Patent Document 2 discloses a structure in which a bypass diode is attached to a heat sink. However, in order to dissipate heat generated from the bypass diode with only this heat sink, a large heat sink is required, and the terminal box is large. There was a problem.
